The suction part (blower) is provided in the rear part, and from the suction opening established in the main body casing, contaminated air (floating particulate matter such as dust and chips, oil mist, etc. is included. Air) is diffused into fine particles and separated by specific gravity (oil droplets) with a collision plate (and / or trap plate), and filtered and separated with a number of stacked filters, and then a high-precision filter and / or trap plate is formed. Thus, oil droplets and / or separation are reliably achieved, oil is captured and clarified air is generated, and this clarified air is discharged from the main body casing to the outside of the main body. Among these, the following prior arts are conventionally mentioned.

The feature is that a filter cleaning nozzle that jets cleaning water to the metal mesh filter of the pre-stage filter device is provided, which prevents the filter from clogging and traps suspended particulate matter well. The provision of equipment.

  In addition, the applicant needs to incorporate a new mechanism that abandons the existing concept in order to clarify air and / or use the processing fluid effectively while separating mist and suspended particulate matter. Intuitively propose a cyclone method. As a separation mechanism adopting this cyclone method, the following document (2) is Japanese Patent Laid-Open No. 7-289951 published on November 7, 1995, and the name of this invention is “Cyclone Filter”. is there. The invention comprises a plurality of individual cyclone members with a common inlet chamber and a common separation chamber, and each two tangential supply tubules between the inlet chamber and the swirl chamber of the cyclone member In addition, the cyclone member is arranged so as to obtain a high degree of symmetry based on the principle of mirror image including the wall of the common separation chamber. In addition, the present invention intends to propose a cyclone filter having a configuration capable of separating particles having a particle diameter smaller than about 1 μm from a dust-containing gas. Reference (3) is Japanese Patent Laid-Open No. 9-19648 published on January 21, 1997, and the name of the present invention is “dust collector”. This invention takes out the dust separation means in which gas flows into a rough gas chamber having a gas inlet containing dust, the clean gas chamber into which clean gas flows from the dust separation means, and the clean gas in the clean gas chamber. A dust collector equipped with a clean gas duct, comprising a gas passage that connects the rough gas chamber and the clean gas duct, and a damper provided in the gas passage. For example, avoid slowing of the swirl flow rate of the gas in the multi-cyclone cell where the gas passage amount is less than the maximum, and avoid the clogging of ash and the occurrence of accumulation in the inclined tube part etc. Intended. Furthermore, it is intended to reduce the size of the dust collector and enhance the dust collection function.
